The UI generating unit 130 generates a user interface (UI) for the user's selection for a plurality of task options which can be supported by the image forming apparatus 12 under the control of the host controller 160.

The UI generated through the UI generating unit 130 may be displayed to a user through the display unit 140.

FIG. 2A through FIG. 2D illustrate an example of the UI generated through the UI generating unit 130.

As illustrated, the UI may include a task set-up button 310, a plurality of task option check boxes 320, a task option add button 330, and a plurality of page set-up buttons 340 and 350 for every task option. That is, the UI may include page set-up menus corresponding to the respective task options for a document.

For example, a user may select the task set-up button 310 as illustrated in FIG. 2A to perform printing. Then, as illustrated in FIG. 2B, a menu including the plurality of task option check boxes 320 is activated. If the menu is checked, the plurality of task options can be selected through the task option add button 330. Then, the user may set up a page corresponding to every task option through the page set-up buttons 340 and 350 activated for every task option.

In the memory unit 150 are stored information on a plurality of task options which are supported by the image forming apparatus 12, the information being transmitted through the host communication unit 110, image data corresponding to the plurality of task options set-up by the user, and the like. The memory unit 150 may be provided as an HDD, a RAM, etc., and stores image data which is set up for a task option in a file format.

The host controller 160 controls entire operations of the host apparatus 11. Specifically, the host controller 160 controls the host communication unit 110 to generate single image data corresponding to the plurality of task options which are input through the user input unit 120 and transmits the image data to the image forming apparatus 12 through the host communication unit 110.

Here, the generated image data includes a header including information on the plurality of task options. The header may be made in the PJL format (Printer Job Language). The task option can be set up in a unit of page of the document.

FIG. 3 illustrates an example of the header of the image data of the PJL format. As illustrated, the image data includes page set-up information for every page for the plurality of task options. For example, a user may set up proof printing for pages 1 through 9 and 15 through 20 and may set up fax transmission for pages 2, 4 and 10 through 16. In this case, one image data generated include information on the plurality of task options in the header thereof.

Alternatively, as illustrated in FIG. 1, the image forming apparatus 12 includes a print communication unit 210, a processing unit 220 and a print controller 230.

The print communication unit 210 performs data communication with the host apparatus 11 under the control of the print controller 230. That is, the print communication unit 210 may transmit the task option information to the image forming apparatus 12 in response to request of the host apparatus 11. The print communication unit 210 may be provided as a wire or wireless communication module which is network-accessible, a USB port or the like.

The processing unit 220 forms an image based on the image data received from the host apparatus 11, and performs tasks corresponding to the plurality of task options included in the image data.

The print controller 230 controls the entire operations of the image forming apparatus 12. Specifically, the print controller 230 interprets the task option information included in the image data received from the host apparatus 11, for every page.

FIG. 4 illustrates an example of the image data interpreted by the image forming apparatus 12.

The image forming apparatus 12 interprets the task option information according to a page ID given to the received image data. For example, in the case that proof printing is set up for pages 1 through 9 and 15 through 20 and fax transmission is set up for pages 2, 4 and 10 through 16 in the host apparatus 11 as illustrated in FIG. 3, the image forming apparatus 12 receives the image data concerned and interprets set-up for the plurality of task options for every page according to the page ID given every page as illustrated in FIG. 4.

Here, if the header of the received image data is made in the PJL format, the print controller 230 can perform PJL-parsing for the header of the received image data to interpret the plurality of task options.

Then, the print controller 230 controls the processing unit 220 to perform operations corresponding to the interpreted task options.
